I have a Droid Eris currently running 2.1 OTA. I don't have another upgrade for like a year and a half. It seems to be running slower and slower. I want to root but don't want to brick my phone and get stuck with some crappy phone till my next upgrade. Can someone point me in the right direction because there are a bunch of different answers on similar threads. I just want my phone to be fast again. Is there a risk free way to root and continue using sense UI and 2.1?
